Can you describe the absorption and distribution of food and nutrients in the plant?

Question

Can you please describe this in detail (not to complicated though, just enough to understand)? Thanks!

Please don't post if you are not certain...

Answer 1

the root system is the part of the plant responsible for absorption of minerals and water in addition to the fixation of the plant. first of all absorption of minerals takes place through an active process called active transport since minerals are present in low concentration in the soilcompared with the concentration of minerals present in the root hair cells therefore the root hair cells have to consume energy in order to take these minerals against their concentration gradient this is why the root hair cells contain a large number of mitochondria which is the power house of the cell that releases energy by a process called respiration second of all the absorption of water occurs through process called osmosis since water is present in high concentration in the soil compared with the concentration of water in the root hair cells as a result water will move from the soil into the root hair cells through a partialy permeable membrane called the cell membrane after allthe absorption happens water and the dissolved minerals willmove along the xylem vessel by three processes cappilary action, root pressure and transpiration (evaporation of water from the leaf creating a suction force which pulls the water coloumn up through the xylem vessel.in the leaf structure the midrib branches into many veins to ensure that all photosynthesising and normal cells are close to the water supply then the main process of transport between the cells is diffusion the movement of molecule from regions of high concentration to regions of low concentration down the concentration gradient.

Answer 2

Roots take minerals (Si, Mg, Mn, Cu, Fe, Ga, Ge, etc) in solution (mixed with water) from the soil. Roots also take oxygen that permeates soil and water too.
Roots also take salts like Na Cl, nitrogen salts, and other from soil.
Then most of these are taken to leaves. There takes place Calvin Cicle to obtain energy from sunlight and with CO2 acquired from the air by leaves and water from the roots, Glucose is formed.
All nutrients, salts and glucose go to cells on leaves and are manufactured into starch (this goes mainly to roots to be stored), aromatic compounds, enzymes, proteins, oils, etc.
Plants store all this on roots, corms, shoots,etc. to use them when in hunger.
Also gives it to the fruits and seeds and there they help to spread the seeds, by animals, mainly.
